Abstract (en)

[origin: WO2019066628A1] Embodiments herein provide a method for handling a user plane by a UE configured for dual connectivity operation. The method includes receiving a RRC reconfiguration message including one or more Layer 2 indications and a Layer 2 configuration corresponding to one or more radio bearers from one of a MN and a SN involved in a dual connectivity operation of the UE. Further, the method includes performing, by the UE, one of: reestablishing of a RLC entity and a data recovery procedure for a PDCP entity corresponding to the radio bearer based on the one or more Layer 2 indications and the Layer 2 configuration received in the RRC reconfiguration message, and reestablishing of a RLC entity and reestablishing of a PDCP entity corresponding to the radio bearer based on the one or more Layer 2 indications and the Layer 2 configuration received in the RRC reconfiguration message.
